The black lines are the paths that were successful. Each station 
beacons every 10 minutes on 10 meters using PSK31, and reports any 
packets heard to the system. The lines are  the actual great circle 
paths the transmission followed. Red stations are those that did not 
receive or transmit successfully in that 10 minute slice...
